Momoh has been struggling with knee pain for several weeks due to an injury suffered last year. As conservative therapy has not shown any improvement tendency in recent weeks, the latest examinations have shown that a surgical intervention is necessary.
The Nigerian striker will undergo surgery in the next days and will be out for a longer period of time. Exactly how long he will be out of action can only be determined after the operation.
"It is unfortunate that we lose an important striker like Francis for several months. We will now monitor the transfer market and see if we can still be active and compensate for the loss of Momoh," said sporting director Bernt Haas.
Grasshopper Club Zürich wishes Francis Momoh all the best for the operation and hopes to welcome him back on the training pitch soon.
